Class XsltTransmogrifier<T>

java.lang.Object

org.openehealth.ipf.commons.xml.AbstractCachingXmlProcessor<Templates>

org.openehealth.ipf.commons.xml.XsltTransmogrifier<T>

All Implemented Interfaces:

Transmogrifier<Source,T>

Direct Known Subclasses:

SchematronTransmogrifier

public class XsltTransmogrifier<T>
extends AbstractCachingXmlProcessor<Templates>
implements Transmogrifier<Source,T>

Xslt Processor transforming a Source into an object of type T. The stylesheet to be used is passed with the zap(Source, Object...) call, however, the Xslt Template object is cached for subsequent transformations using this stylesheet.

Xslt parameters can be passed in as Map parameter.

Note: This class is thread-safe and reentrant.

Parameters:

outputFormat - currently supported: String, Writer, OutputStream

staticParams - static Xslt parameters

Method Details

getFactory

public TransformerFactory getFactory()

getCache

protected ConcurrentMap<String,AbstractCachingXmlProcessor.Loader<Templates>> getCache()

Specified by:

getCache in class AbstractCachingXmlProcessor<Templates>

Returns:

static cache for the configured resource type. Note that the returned Map is not necessarily synchronized.

zap

public T zap(Source source,
 Object... params)

Converts a Source into a Result using a XSL processor.

The XSL stylesheet resource location is mandatory in the first extra parameter. XSL Parameters may be passed as a Map in the second parameter.

Specified by:

zap in interface Transmogrifier<Source,T>

Parameters:

source - what goes in

params - parameters

Returns:

what comes out

See Also:

• Transmogrifier.zap(java.lang.Object, java.lang.Object[])

setXsltParameters

protected void setXsltParameters(Transformer transformer,
 Map<String,Object> param)

Sets the parameter to the Transformer object

createResource

protected Templates createResource(Object... params)

Description copied from class: AbstractCachingXmlProcessor

Creates a ready-to-use resource (e.g. an XML Schema instance) for the given key. Insertion into the cache will happen externally, this method's purpose is only to instantiate the resource to be cached.

This method does not need to be re-entrant, but its result MUST be thread-safe.

Specified by:

createResource in class AbstractCachingXmlProcessor<Templates>

Parameters:

params - validator/transmogrifier parameters.

Returns:

resource of the configured type.

getStaticParams

public Map<String,Object> getStaticParams()

setStaticParams

public void setStaticParams(Map<String,Object> staticParams)
